1.	Consider a circular road of radius 20 meter banked at an angle of 15 degree. With what speed a car has to move on the turn so that it will have safe turn?
Answer» Solution :`v = SQRT(vg tan THETA) = sqrt(20 xx 9.8 xx tan 15^@) = sqrt(20 xx 9.8 xx 0.26) = 7.1 m//s` The safe speed for the car on this road is `7.1 ms^(-1)`
